Functions
This chapter contains information about the File Manager functions that you can use to perform File Manager tasks. It also contains information about the File Manager-supplied REXX external functions that can be used in REXX procedures and template criteria expressions run within File Manager.
The File Manager functions can be invoked from batch jobs using JCL, within TSO as commands, and from REXX and CLIST procedures. The REXX external functions are only made available to a REXX environment running under the control of a File Manager function.
